pplcation led April 17, 1912.y Serial No. 691,376.

To allwiom, it may concern:

Be itk known that we, MARIE EUGNE MAURICE'HAGNAUER and JEAN JOSEPH HIP--"projeetenapd the like and refers particu larly to lampsiintended for`use upon the s bodies of ordinary carriages"andrinorenes pecially uponthe bodies oiv motor cars.

The invention is, moreover, parti"curar-lyY suitable for use with vthatclass of such lamps in which a cylindrical device is pro-- vided foracting as a lamp carrier and facilitating the mounting of the lamp.

The particular object of the invention v*is to so construct the,aforesaid articles that, contrary to the usual practice, they may bemounted without providing any separate ineans for carrying them, and toso construct them that they can be mounted upon any surfaces no matterwhat the conformation of such surfaces may be.

The principle of the invention consists in forming the cylindricaldevice which, in the usual way serves for mounting the object, from somepart of the object itsel.

The invention refers more particularly to certain methods of carryinginto practical effect the arrangement-s just'mentioned and includes moreespecially as new industrial products, articles of embodying the saidarrangements, special partsl suitable for making up the articles withsuch articles.

The invention will be'readily understood with the assistance of thefollowing description and the annexed drawings which are, however, givenmerely by Way of examples of methods of carrying out the invention.

Figures 1 and 2 of the drawing are elevations with parts removed of anelectric lamp and an acetylene la mp respectively constructed accordingto the invention; Fig. 3 is a perspective view on a much smaller scaleof the front portion of a motor car.

with a body of the torpedo type having the kind in question,

mounted thereon two lamps similar to that shown in Fig. Q-only one osuch lamps being visible in the ligure. v

According to the particular method of carrying out the inventionillustrated in the drawing in mounting a lantern upon a carriage bodyive-proceed substantially as follows: We provide a cylindrical bodywhich forms the casing a of the lamp, that is the portion which containsthe working parts, namely the refiector l and the lamp or the vburifierb1. The body may also be formed or provided with a shade or hood b2.rThis Patented J une i6, Mite. y

cylindrical body-which in the case where v the lamp is intended for useas an acetylene lamp may also with advantage serve. as a Wsupportfor theburner 72b-is of such length Ythats-for thefpurpose ofmounting the lampthe rear end of the body can he so cut that it can be itted to thesurface a to which the lamp is to be attached no matter what may be theconformation of' such surface and may be riveted or otherwise attachedWith the assistance ior instance oic tongues a1 yformed when cuttingaway the tube or by means of a turned up or flanged edge pro ducedsubsequently to such cutting, By this construction a lamp is producedwhich cany be mounted under all circumstances without resorting to anyauxiliary device, a method which is much simpler and much moreeconomical than thc present systems: in the case of which when it isdesired to mount a lamp with the assistance of a cylindrical lampcarrier it has been necessary to provide a special cylindrical body incoiinection with the working parts and thc container.

` What we claim and desire to secure by Letters Patent of the UnitedStates of America is 1. As a new article of manufacture, a lampconnirising a hollow, approximately cylindrical element which open atits rear end, is elongated rearwardly, and constitutes the entire bodyof the lamp, and a form to some suitable point'on the surfaceA of thebody to which the lamp is to be attached, whereby said cut end may befasdevice and a reflector for the tened directly to said body at suchpoint and the use of separatevsupporting devices Vfor the lamp isavoided.

2. As a new article of manufacture, a lamp havingpits body constitutedsolely by a hollow, approximately cylindrical element which is elongatedrearwardly, the rear end of said elongated p ortion being adapted to be'turned outwardly to produce attaching means conforming to the surface ofthe body to which the lamp is to be attached at some suitable point onsaid body, said attaching means being designed to be fastened .directlyto said body at such point, whereby the use of separate supportingdevices for the lamp is avoided.

3. As a new article of manufacture, a lamp comprising a hollow,approximately cylindrical element which is elongated `axi-A ally in arearward direction and constitutes theentire body of the lamp, and a1ightemitting device and a reflector for the same mounted directlyWithin and secured to the cylindrical element at the front end thereof,the rear end of said cylindrical element being adapted to be turnedoutwardly to produce attaching means designed to be fastened directlyagainst the body to which the lamp is to be attached, whereby the use ofseparate supporting devices' for the lamp is avoided. y

v In testimony whereof, We alix our signatures, in presence of twoWitnesses.
